Using a database of precomputed hashes from sequentially calculated passwords called a rainbow table, an attacker can simply look up a hashed password and read out the text version. Each column in the rainbow table uses a different reduction function. The function of the table is <span>reversing cryptographic hash functions. </span>

Explanation:
triangle_char = input('Enter a character: ')
triangle_height = int(input('Enter triangle height: '))
print('')
for j in range (triangle_height):
print((triangle_char) * (j + 1))
#below are sample output that can be gotten with predefined values
$ ./triangles.py
Enter characters: jk
Enter height: 8

Sharpeners.
Explanation:
'What makes a great Technical Drawing? ' Technically correct, accurate, complete, consistent and unambiguous. Check the brief (a lot – and at all stages of the drawing process).
In Python, a string is an array of characters, we can access these characters using index operator []. For example, we have a_string = "Hello World" a_string[0] prints the first character in string ('H').
We can also use index operator to make substrings, for example a_string[0:3] will make a substring with first, second, third and fourth character equal to "Hell".
Now to business
my_string = "This is MY string!"
print(my_string[0:7]) # Prints "This is "
print(my_string[0:7:5]) # Prints "T" then prints the sixth character since we start counting at 0 hence prints "Ti" (note that space is also a character).
Hope this helps.
